A new drone from Parrot does double duty, flying through the air like any other quadcopter but converting in a snap to propel a small hydrofoil boat. By attaching the drone perpendicular to the body of the boat, the gadget sends its thrust rearward instead of down, causing the boat to move forward and rise up on its little pontoons.
When the motors are started, the top of the hydrofoil rises and is positioned perpendicularly to the nautical structure.The hydrofoil then slides on the water and then holding at 5/6 cm above with surprising stability and dexterity.
Limiting the water resistance, it can reach a maximum speed of 5.4 knots and turn in an instant without capsizing.
